import time
import gevent
n = 1000000
def worker():
    for _ in range(n):
        gevent.sleep(0)

start_time = time.process_time_ns()

greenlet = gevent.spawn(worker)

for _ in range(n):
    gevent.sleep(0)

end_time = time.process_time_ns()

switch_time = (end_time - start_time)/(2*n)
print("Context switch time:", switch_time, "ns")

Is there a better way to measure loop scheduling time? Or does gevent itself provide this metric?
